What Is Recurrent Ovarian Cancer?

Recurrent ovarian cancer means the cancer has returned after a period of remission (when there was no evidence of disease in the body)^[1]. The cancer can come back in the same area where it started, in nearby structures or lymph nodes, or in a completely different part of the body^[6]. Sometimes, cancer can recur in multiple places at once.

Recurrent ovarian cancer is treatable but rarely completely curable^[1]. However, advances in therapies allow many people to manage it as a chronic illness, similar to diabetes or heart disease. This means you may have periods when the cancer is controlled, followed by times when additional treatment is needed.

How Common Is Recurrence?

Recurrence is common with ovarian cancer. Research shows that between 70% and 80% of people treated for ovarian cancer will experience a recurrence after their initial treatment^[2]. This high rate is partly because ovarian cancer is often difficult to detect early and doesn’t always cause symptoms in its beginning stages. About 80% of ovarian cancers are not diagnosed until they have reached a later stage^[2].

The likelihood of recurrence depends heavily on the stage of cancer at the time of your original diagnosis^[1]:

Stage 1: 10% chance of recurrence
Stage 2: 30% chance of recurrence
Stage 3: 70% to 90% chance of recurrence
Stage 4: 90% to 95% chance of recurrence

If your ovarian cancer was initially diagnosed at an earlier stage, it is less likely to come back^[2].

When Does Recurrence Occur?

Recurrence can technically happen at any time, from weeks after treatment to years later^[6]. The amount of time between the end of treatment and when cancer returns is called progression-free survival^[2].

For most people with ovarian cancer, the average progression-free survival is 16 to 21 months^[2]. About 80% of people experience a recurrence within 18 months of treatment^[6]. However, in cases of highly chemotherapy-resistant cancer, recurrence can happen during the weeks following treatment. Cancers that are highly sensitive to chemotherapy may disappear for years before recurring^[6].

The median interval to first recurrence is 18 to 24 months^[9]. The timing of recurrence is an important factor that helps doctors plan your treatment approach.

Signs and Symptoms of Recurrence

Recurrent ovarian cancer may cause the same symptoms as the original cancer, or the symptoms may be different^[2]. The most common symptoms include:

Fatigue
Sleeping problems
Pain
Nausea
Bowel changes
Bloating

When ovarian cancer recurs close to the original site in the abdomen, typical symptoms may include^[7]:

Belly pain
Bloating
Nausea or vomiting
Problems going to the bathroom

Other symptoms can include unexplained vaginal bleeding, unusual vaginal discharge, pain or pressure in the pelvis or lower abdomen, and unusually frequent urination^[6].

Once you have been treated for ovarian cancer, you will need regular follow-up appointments with your doctor to check for signs that the cancer has returned^[2]. During these visits, your doctor may check your blood for certain substances that could suggest tumor growth, such as CA-125 (a protein in the blood)^[7]. You may also get imaging tests like X-rays, CT scans, or PET scans if something seems wrong.

It is important to tell your doctor about any unusual changes you notice in your body—don’t wait for your next appointment^[7].

Treatment Options for Recurrent Disease

Your treatment options depend on several factors, including what type of ovarian cancer you have, where the cancer is in your body, what treatment you’ve already had, when you last had treatment, and how well you are^[4]. Your treatment approach should be discussed with your gynecologic oncologist (a doctor who specializes in cancers of the reproductive system), considering factors such as treatment options, clinical trials, side effects, quality of life, and personal goals^[1].

Chemotherapy

Chemotherapy uses anti-cancer drugs to destroy cancer cells. The drugs circulate throughout the body in the bloodstream^[4]. You will probably be able to have chemotherapy even if you already had some at an earlier stage.

When ovarian cancer comes back, doctors usually describe it as either platinum sensitive or platinum resistant^[4]. This classification depends on how long it has been since you last had a platinum chemotherapy drug like carboplatin.

Platinum sensitive means your cancer has come back 6 months or more after your last carboplatin treatment^[4]. Your specialist usually suggests you have carboplatin again, sometimes with another chemotherapy drug such as paclitaxel, liposomal doxorubicin, or gemcitabine. You might be able to have this treatment multiple times over many years.

Platinum resistant means your cancer comes back within 6 months of finishing your last carboplatin treatment^[4]. It is unlikely that you will have carboplatin again. Your specialist may suggest one or more treatments such as paclitaxel (usually as a weekly treatment), liposomal doxorubicin, gemcitabine, topotecan, etoposide, or cyclophosphamide.

Surgery

Surgery may be an option for some people with recurrent ovarian cancer. This additional surgery, called secondary cytoreduction, aims to remove as much of the cancer as possible before starting chemotherapy again^[15].

Patients with single site recurrence and a long disease-free interval are candidates for secondary surgery, which may provide longer survival^[9]. However, results from clinical trials show that not everyone benefits from this approach. Surgery is most helpful for patients who meet strict criteria and when a skilled surgeon can remove all visible disease^[15].

If your care team feels that secondary surgery is not likely to be successful in removing all signs of the cancer, you should not be exposed to a potentially harmful surgical treatment^[15].

Targeted Cancer Drugs

Targeted therapies are designed to attack specific characteristics of cancer cells^[5]. These may include PARP inhibitors, which are given to patients after chemotherapy to try to keep them in remission^[14].

Hormone Therapy

Hormone therapy may be an option for some types of ovarian cancer^[4].

Clinical Trials

Clinical trials are research studies that test new treatments or therapies for cancer^[16]. They may give you access to new treatments that are not yet widely available. If you are interested in joining a clinical trial, talk to your doctor about how to do so.

Understanding Your Outlook

If your ovarian cancer comes back, your doctor may estimate your prognosis, or outlook^[2]. Certain factors may indicate a better prognosis following a recurrence, including:

Younger age at the time of initial surgery
A longer window of time between the end of first-line therapy and relapse
Successful removal of more of the tumor during initial surgery
Successful application of combined treatment with optimal surgery, chemotherapy, and/or radiotherapy

Overall survival rates depend on the type and stage of ovarian cancer. The five-year relative survival rate for epithelial ovarian cancer is about 50%. For stromal cancer, the five-year relative survival rate is 89%, and for germ cell tumors, it’s 92%^[2].

Recurrent ovarian cancer has worse overall survival rates than newly diagnosed cancer. The median time people live after having an ovarian cancer relapse is two years^[2]. However, these statistics don’t predict what your outcome will be. Your doctor can help you get a better understanding of your outlook based on your individual characteristics.

It is important to remember that every individual’s situation is unique. Statistics are broad representations and do not dictate personal outcomes^[1]. Many people with recurrent ovarian cancer can live a normal life for a number of years^[4].

Coping with Recurrence

Finding out that your cancer has come back can be a big shock and may be very difficult^[4]. It is natural for your mind to jump to worst-case scenarios. You might feel frightened, uncertain, frustrated, sad, guilty, or exhausted^[1].

A recurrence can be emotionally and physically challenging^[16]. Getting support from family, friends, and healthcare providers can help you manage the stress and future unknowns. Consider joining a support group or speaking with a therapist who is trained in cancer care.

Give yourself permission to feel your emotions. Remember that feelings don’t define who you are^[20]. Pay close attention to your feelings and recognize what triggers them. This will help you better understand these feelings should they arise again. Stay in close contact with your support group, caregivers, and healthcare team and let them know how you’re feeling.

Your healthcare team will talk to you about your test results and discuss your treatment options and what they involve. They will explain more about the aim of treatment and help you make decisions^[4]. Talk to your doctor or specialist nurse to understand:

What your diagnosis means
What is likely to happen
What treatment is available
How treatment can help you
What the side effects of the treatment are

You might feel that you don’t want to know much information straight away. Tell your doctor or nurse. You will always be able to ask for more information when you are ready^[4]. Everyone is different and there is no right way to feel.

Taking steps to maintain a positive outlook can help. Make healthy choices by moving your body, maintaining a healthy diet, staying hydrated, and getting rest—work with your doctor to determine what’s appropriate for you^[20]. Reach out to professional help such as a counselor or therapist, family and friends, other people with cancer through online forums or events, and ovarian or gynecologic cancer advocacy groups.
